UPDATE: One person was injured Wednesday when intruders in an SUV allegedly tried to ram through a barrier at the Maryland military base where the National Security Agency is headquartered — and gunfire broke out, officials said.

"Several individuals" were taken to area hospitals following the shooting at the Fort Meade security gate, which happened around 7 a.m. ET, they said.

"Preliminary reports do not presently indicate that there are injuries attributable to gunfire," a Fort Meade public information officer said at the scene.

In an earlier statement, the NSA said "the situation is under control and there's no ongoing security or safety threat."

The FBI in Baltimore tweeted that it was "aware of the incident" and was sending personnel to respond.

Federal authorities did not identify the alleged intruders or the injured persons.

But aerial footage obtained by NBC Washington appeared to show a black SUV with bullet holes in its windshield — and deployed airbags — that looked to have crashed into a concrete barrier.

At least one handcuffed man was on the ground, surrounded by police, NBC Washington said.

The #FBI is aware of the incident at Fort Meade and we are sending personnel to respond at this time. Continue monitoring @FBIBaltimore for updates.

In the wake of the shooting, the Maryland State Police closed a nearby major highway in both directions, causing massive traffic tie-ups and turning the morning commute into a nightmare.

In a statement, the White House said that President Trump had "been briefed on the shooting at Ft. Meade."

"Our thoughts and prayers are with everyone that has been affected. We will continue to provide updates as they become available," the statement added.

This is not the first incident to happen at an NSA security gate. In March 2015, two unauthorized people tried to enter with a stolen SUV. NSA police fired at the vehicle, killing one suspect and injuring the other, NBC Washington reported.
